Ion beam modification of magnetic tunnel junctions
B. M. S. Teixeira, A. A. Timopheev, N. Caçoilo +6
The impact of 400 keV ion irradiation on the magnetic and electrical properties of in-plane magnetized magnetic tunnel junction (MTJ) stacks was investigated by ferromagneti…
Second order anisotropy contribution in perpendicular magnetic tunnel junctions
A. A. Timopheev, R. Sousa, M. Chshiev +2
Magnetoresistance loops under in-plane applied field were measured on perpendicularly magnetized magnetic tunnel junction (pMTJ) pillars with nominal diameters ranging from 50 to 1…
Respective influence of in-plane and out-of-plane spin-transfer torques in magnetization switching of perpendicular magnetic tunnel junctions
A. A. Timopheev, R. Sousa, M. Chshiev +2
The relative contributions of in-plane (damping-like) and out-of-plane (field-like) spin-transfer-torques in the magnetization switching of out-of-plane magnetized magnetic tunnel…
Dynamic exchange via spin currents in acoustic and optical modes of ferromagnetic resonance in spin-valve structures
A. A. Timopheev, Yu. G. Pogorelov, S. Cardoso +3
Two ferromagnetic layers magnetically decoupled by a thick normal metal spacer layer can be, nevertheless, dynamically coupled via spin currents emitted by the spin-pump and absorb…
Anomalous Hall effect in two-phase semiconductor structures: the crucial role of ferromagnetic inclusions
A. V. Kudrin, A. V. Shvetsov, Yu. A. Danilov +5
The Hall effect in InMnAs layers with MnAs inclusions of 20-50 nm in size is studied both theoretically and experimentally. We find that the anomalous Hall effect can be explained…
Direct and converse magnetoelectric effects in Metglas/LiNbO3/Metglas trilayers
A. A. Timopheev, J. V. Vidal, A. L. Kholkin +1
Electromechanical and magnetoelectric properties of Metglas/LiNbO3/Metglas trilayers have been studied in the frequency range from 20 Hz to 0.4 MHz. A trilayer of Metglas/PMN-PT/Me…
